CVE-2025-41408

Improper authorization in handler for custom URL scheme issue in Yahoo! Shopping App for Android versions prior to 14.15.0 allows a remote unauthenticated attacker may lead a user to access an arbitrary website on the vulnerable App. As a result, the user may become a victim of a phishing attack.

Weakness

The product uses a handler for a custom URL scheme, but it does not properly restrict which actors can invoke the handler using the scheme.

Potential Mitigations

• Utilize a user prompt pop-up to authorize potentially harmful actions such as those modifying data or dealing with sensitive information.
• When designing functionality of actions in the URL scheme, consider whether the action should be accessible to all mobile applications, or if an allowlist of applications to interface with is appropriate.
